TURBINE-GATE.

Specification of Letters Patent.

Patented Jan. 18, 1921.

Application filed February 18, 1920. Serial No. 359,613.

To all whom it may concern.

Be it known that I, JOHN H. FEurHoUsnN, a citizen of the United States, residing at York, in the county of York and State of ennsylvania, have invented new and useful Improvements in Turbine-Gates, of whlch the following is a specification.

' This invention relates to turbines and particularly to wicket gates therefor The purpose of the improved wlcket gate embodying the features of the present invention is to materially reduce the cost of production and the expense of repair by building up or fabricating a gate n such manner that its components or parts Wlll uniformly contribute to the formation of a stronger and more durable gate with less labor, and one which is considerably lighter and stronger and more durable in its organization, and requiring less force or power to actuate a group of the gates when installed in a turbine, and also to have the stem and pivot or fulcrum means of each gate so constructed as to give the best results as to torsional strain and wearing resistances, and also capable of being expeditiously repaired and replaced.

The invention consists in the construction and arrangement of the several parts hereinafter described and claimed.

In the drawings:

Figure 1 is a sectional elevation of a wicket gate and stem embodying the features of the invention.

Fig. 2 is a top plan View of the gate and stem.

Fig. 3 is a perspective view showing the manner of bending the outer inclosing member or metal sheet over the interior structural features and including the stem of the improved gate.

The gate stem in accordance with the present invention is of composite form and comprises an upper operating member 5,'an intermediate body member l9-and a lower fulcrum member 5?. The composite stem has upper and lower and intermediate ribs 24, 25 and 21 suitably-associated therewith, or secured thereto in any preferred manner, and inclosing the intermediate body part or member'19 of the stem and the said ribs is an outer casing 8 which is bent into shape over the said ribs and'secured to the latter, reinforcing rivets or bolts 9 being also inserted through the gate at intervals as may be found necessary. stem extends through the center of and the upper operating member 5 projects above the upper end of the gate a sufficient distance and has secured. thereto an operatlng crank 10 adapted to be connected in any well known manner to a gate operating ring The lower pivot or fulcrum member 5 of the stem is arranged to engage with a base or other adjacent part of the turbine frame or casing adapted for the purpose. The upper operating member 5 of the stem is of cast steel and either formed from a primary tubular length of this metal or suitably bored, and the lower or pivot or fulcrum member 5* is of the same metal as the upper member and is likewise either primanly tubular or longitudinally bored, and between the upper and lower cast steel members of this stem the body member 19 is interposed, said body member being of a lower grade metal such as cast iron and tubular. The bores of the members 5 and 5 are in alinement with and are adapted to form continuations of the opening through the intermediate body member 19. By this means the lower pivot or fulcrum member 5" may be conveniently lubricated from the upper portion of the gate.

The ribs 24, 25 and 21 are secured to or formed as parts of the intermediate body member 19, the ribs 21 being shorter than the upper and lower ribs 24 and 25, and the number of these intermediate ribs may be increased as desired. By disposing the rib 24 near the upper end of the gate, the upper stem member 5 is reinforced or strengthened and the torsional strain incident to the operation of the gate through this part of the stem is more evenly distributed and more positively resisted, particularly at the said upper end of the gate where the torsional strain is the greatest. The lower pivot or fulcrum member 5* is also reinforced and strengthened by the lower rib 25, and the stresses transmitted to the gate through the said pivot or fulcrum member are also more evenly distributed by the'said rib.

The intermediate member 19 has two of the intermediate ribs 21 associated therewith and it will be understood that the illustration of the two intermediate ribs 21 indicate that any number of these ribs may be used. The ribs 21 extend only partially toward the opposite rear and front edge the gate,

The improved composite portions of the casing or body 8, and at the upper and lower ends of the intermediate stem member 19 are heads 22 and 23 which have their respective upper and lower faces dressed off or machined, to render the same smooth, and connected to ribs 24 and 25 which are also dressed or machined off at the central portions adjacent to the respective upper and lower faces of the heads 22 and 23, bolts 26 being passed through the heads 22 and 23 and ribs 24 and 25 so as to securely unite the several members or components of the stem. The ribs 24 and 25 are secured to the upper stem member 5 and lower pivot or fulcrum member 5";

and the bore 27 through the intermediate bodymember 19 is formed of larger diameter than the bore through the upper extension member and lower pivot or fulcrum member of thisstem, so that when the parts are assembled the bores of the several members will aline and serve as a conduit means for lubricants therethrough for'the purpose of lubricating the lower pivot or fulcrum member at its bearing. The bores of the members 5 and 5" are continued through the ribs 24 and 25, as shown in dotted lines in Fig. 1. It will be understood that the intermediate ribs 21 will have securing rivets or bolts 20 inserted therethrough and through the opposite side portions of the casing 8.

What is claimed as new is:

1. A wicket gate of the class specified consisting of a composite stem made up of upper and lower members of a relatively high grade of metal, and an intermediate member of a lower grade of metal secured to the upper and lower members, and an inclosing sheet metal casing bent around the stem and attached to the latter.

2. A wicket gate of the class specified consisting of a composite stem having memoers of relatively higher and lower grades of metal all formed with longitudinal openings therethrough which are in alinemcnt, the parts of the stem carrying rib devices, and a sheet metal inclosing casing bent around and secured to the said rib devices.

In testimony whereof I have hereunto set my hand in presence of two subscribing \vit- IIGSSGS.
